Pareto Principle

The Pareto principle is the 80/20 rule - most results come from a small slice of effort.

Key Concept

• Named for Vilfredo Pareto (roughly 80% of results from 20% of effort - shorthand, not a law).
• Level 1: Roughly eight out of ten results often come from two out of ten of your effort - like most of the apples on one branch of the tree, not spread evenly on every twig.
• Level 2: Pareto principle is shorthand - roughly eighty percent of results from twenty percent of effort, named for Vilfredo Pareto.
• Level 3: Most outcomes cluster in a minority of inputs - the ratio is a heuristic for where to spend disproportionate focus.
• Level 4: List your top three outputs last month - find which inputs produced them and protect that slice before you optimize the rest.
• Level 5: Low Hanging Fruit and Minimum Effective Dose apply the same skew - not a law, but a lens before you spread hero energy evenly.
• I use it when my reading list, task board, or note tags all feel equally important: which few actually moved the needle?
• Same rule for flashcards: only spine notes carry review: true here
• PKM habits plus six Eternal Principles with cards, not every faith note in the garden.
• Cards ask what I would do, not what I would define.

Examples

• The kids' activity list had six things and we skipped three nights - I trimmed to basketball and piano and we actually showed up.
• My reading pile had forty tabs - the five that moved work got Sunday morning, the rest got deleted.
